TJ O'Donnell Gallery of Art

Artist, Scientist, Consultant in Scientific Computing and Visualization

The images shown here were created as a result of inspiration while working on routine scientific tasks. As I become saturated with the scientific aspects of the work, my mind begins to see the data in more artistic ways. While not losing touch with the scientific underpinnings of the data itself (I never corrupt the data "for artisitic purposes") I allow myself to be free of the constraints imposed by the traditions of scientific illustration and didactic clarity.

I typically begin with some scientific information, often a molecular structure of some kind. I use the Gramps general-purpose graphics language on a SGI/Iris to interactively create the images I want, slowly adding interesting features and removing others. I may add other relevant pieces of data, such as a surface which might represent an electron density or a potential energy isocontour. Finally, I use Gramps to output a file of instructions for a ray-tracing program, such as Tom Palmer's RayT or rayshade. I hope you enjoy looking at these images, whether its the scientific or artistic content that appeals to you more.

I have also collaborated with the Artⁿ Laboratory using my images to make PHSColograms. You can find several samples, beginning here.
